Electrode rolling apparatus having heating unit for heating non-coated portion and electrode manufacturing system comprising the same

An electrode rolling apparatus comprising:

• a sensing unit positioned above an electrode for a secondary battery that is configured to be transferred along a lengthwise direction, to measure a distance between the sensing unit and the electrode for each location along a widthwise direction of the electrode;
• a control unit configured to identify a location of a non-coated portion formed on the electrode using information associated with the distance between the sensing unit and the electrode measured through the sensing unit, and configured to output a control signal to heat a region in which the identified non-coated portion is formed based on the information received through the sensing unit;
• a heating unit positioned above the electrode to selectively heat only the region in which the non-coated portion is formed according to the control signal of the control unit;
• and
• a rolling unit configured to roll the electrode having the selectively heated region in which the non-coated portion is formed.
